Application of Single Frequency Network to the Automatic Hydrological Forecast System of Hongfeng Hydropower Plant

Cao Nianhong

Abstract

The single frequency network (SFN) is the key technology in very high frequency (VHF) channel transmission of automatic hydrological forecast systems. This paper introduces the NARI remote transmission special protocol (NARI/SP) and its application to the automatic hydrological forecast system of the Hongfeng Hydropower Plant. Some effective strategies are designed for remote route control and data transmission in the Hongfeng Hydropower Plant, to meet the requirements for saving frequency resource and improving system operation and maintenance efficiency.
